config: switch cc with libc in the config order

Some of the compiler options depend on the C library choice, (e.g.
whether core passes are needed).

Since the compiler menu comes before the C library menu, those options
may or may not be visible until the C library is chosen, leading to
either options being visible by the user (thus be puzzling as they would
not apply to his case), or invisible to him (yet again puzzling him).

Invert the order of the compiler and the C library in the menuconfig. It
anyway looks more rational, in the end.

cc/gcc: allow CC_EXTRA_CONFIG_ARRAY on baremetal

The final bare-metal compiler is built using the core backend.
Currently the core uses the CC_CORE_EXTRA_CONFIG_ARRAY variable.

While this works as supposed to, this can leave the user puzzled
in the menuconfig, since all he can see is the core options, not
the final options.

Only show the core options if any of the core passes are needed,
and use the final options in the core-backend if we're issuing
the bare-metal compiler.

cc/gcc: avoid passing --enable-multilib

Some versions of gcc have a broken --enable-multilib flag. As multilib is the
default, only pass the --disable-multilib flag

TODO: remove some items

Those items have now been implemented:

- mingw32 target
we have it now, and even mingw64 too

- mingw32 host
it is certainly possible to canadian-build a toolchain to run
in a mingw host

- Cygwin host
it is possible to build a toolchain in Cygwin, and it is probably
possible to canadian-build it as well
